I've noticed from reading a few papers that people with ArcGIS can count pixels in a selected area on a DEM.  Is there any to do that in GM?

    Hello,

    Here is something you can do:
    1. Select your DEM in the Control Center
    2. Right-click and choose Create Point Features at Elevation Grid Cell Centers
    3. On the Select Area to Create Points From window, Draw a Box for the area.
    4. Click OK
    5. A new layer containing points will be created.  
    6. Look at the point count for the layer in the Control Center, or the LiDAR Point Count in the layer metadata.
    If you want to get the number of points in a non-rectangular feature, draw the feature and then select it.  On the Select Area to Create Points From window, choose Crop to Selected Area Features.

    Cheers,

    Bob

    Thanks, I didn't know you could do that.  Will give it a try.
  • Is there anyway to Create point features at elevation grid cell centers for every 10th cell instead of placing it in every single cell? Thanks.
